Compiling spring (mingw and visual studio 7/8)

[ivand]

OMG, I hardly regret that I've chosen MSVC2005. I've lost this day fighting with f***in' manifest tool. It's really piss me off.

Does mingw have adequate IDE and debugger?

[BrainDamage]

codeblocks as IDE and gdb as debugger

[FLOZi]

Or DevCPP

Unitsync wont compile in VS2005, the project needs converting from VS2003 and after correcting all the project library paths it complains of unresolved external symbols.

[AF]

Code: Select all

	bool ValidIndex(int idx) const {
		return ((idx >= 0) && (idx < sounds.size()));
	}

In unitdef.h, cna this be changed? Its annoying seeing 20 or so of these warnings when you compile an AI.

[Tobi]

Changed to what?

Which warnings?

[imbaczek]

guessing - unsigned comparison.

[AF]

sounds.size() is unsigned
idx is signed

I'm getting some compile errors in LuaBinder.cpp. Essentially, it's failing to find the Lua related includes. I'm using scons and have not modified the SConstruct file. I'm getting the error in revsion 4177

[Tobi]

Maybe try a reconfigure, that may fix it.

[ILMTitan]

that worked. Thanks.

[Satirik]

where can I find the Command.h file ?

[imbaczek]

rts/Sim/Units/CommandAI

[Satirik]

edit : nevermind

[AF]

The unitsync project still have a VS2003 project and no VS2005 project file.

Its also out of date and wont compile citing numerous unresolved references to lua. What files need adding to the project?

[Tobi]

Look in SConstruct

[AF]

I just did and re-added all the lua src folder and added 2 files I was missing earlier luautils.cpp and luaparser.cpp. I also added an include folder. I also added the missing GameVersion.cpp

Now lua compiles without the unresolved stuff.

1>unitsync - 1 error(s), 1115 warning(s)

most of which involve lua_number and loss of data or precision.

The problem preventing compilation completing:

Code: Select all

removing gameversion.cpp results in an unresolved reference to it followed by hundreds of lines of unresolved references to lua. VS2005 counted several hundred of these.

It seems most of these are externs inside lua.h

for example:

Code: Select all

/*
** basic stack manipulation
*/
LUA_API int   (lua_gettop) (lua_State *L);
LUA_API void  (lua_settop) (lua_State *L, int idx);
LUA_API void  (lua_pushvalue) (lua_State *L, int idx);
LUA_API void  (lua_remove) (lua_State *L, int idx);
LUA_API void  (lua_insert) (lua_State *L, int idx);
LUA_API void  (lua_replace) (lua_State *L, int idx);
LUA_API int   (lua_checkstack) (lua_State *L, int sz);

LUA_API void  (lua_xmove) (lua_State *from, lua_State *to, int n);

where LUA_API is a macro for extern. There is no documentation specifying a location for the declarations of these externed variables and sconstruct does not say where they are either.

I have still not found the solution to the GameVersion.cpp issue either.

[Tobi]

Turn off precompiled headers for GameVersion.cpp (all configurations), that should do the trick.

I'd say ignore the warnings, conversion from size_t to int and from int to float (which is LuaNumber IIRC) are perfectly fine in a library like unitsync IMHO.

Btw feel free to commit the converted and fixed project file once it compiles in all configurations (use batch build). (don't bother fixing warnings)

greetings,
having a problem compiling Spring with mingw under Windows.

D:\Dev-Cpp\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -lstreflop
collect2: ld returned 1 exit status
scons: *** [game\spring.exe] Error 1
scons: building terminated because of errors.

Can't post full report yet.

I read that several pepole have encountered this before and managed to overcome it by renaming streflop.a to libstreflop.a
But in my case no such file was produced. Someone also mentioned getting streflop.a from other source, but it isn't present in svn.
Thanks in advance
